In this paper,we propose a bit serial arithmetic unit for arbitrary precision.It calculates 1 digit ev- ery cycle from the most significant bit.And when necessary calculation precision is obtained,the calculation is ended.Therefore,there is no need to perform unnecessary calculation,and this may lead to the improvement of throughput and the reduction of power consumption.Also,since 1-bit width arithmetic unit is used without using a general 32-bit or 64-bit width one,the area is small.At first,we describe algorithms of four arithmetic operations that can calculate in arbitrary precision,and then we implemented it in Verilog HDL.Finally, using the MAC
(Multiply-Accumulate) operation that is often used in digital signal processing,we evaluated throughput,power consumption and area. |
